Description

Technical Field

[0001] This utility model relates to the field of impeller manufacturing technology, specifically to a rough milling device for impeller manufacturing. Background Technology

[0002] An impeller can refer to either a wheel disk equipped with moving blades, which is a component of the rotor of an impulse steam turbine, or it can refer to the wheel disk and the rotating blades mounted on it. Impellers can be classified according to their shape and whether they are open or closed.

[0003] Existing milling equipment generates vibrations when machining impellers, resulting in rough blade surfaces and frequent chipping at the leading and trailing edges of the blades, which affects the product qualification rate.

[0004] As disclosed in Chinese Patent CN216151799U, an anti-vibration milling device for ultra-thin blades of an integral impeller is proposed. By starting the cylinder, the cylinder drives multiple sets of first and second mounting boxes to move relative to each other simultaneously through the transmission of the rack plate, the first gear, the support shaft, the turntable, and the connecting rod. This can clamp the impeller. When the impeller size is smaller than the turntable, the above operation steps are still performed. After the above operation steps are completed, the rotating shaft is rotated, which drives the second gear to rotate. Through the meshing of the second gear with the rack set at the bottom of the connecting plate, the connecting plate can be moved horizontally, thereby adjusting the position between the clamping plate and the impeller. After the adjustment is completed, the screw is rotated to make the clamping teeth mesh with the gear ring, thereby restricting the rotation of the rotating shaft, thus limiting the position of the clamping plate.

[0005] However, in the existing technology, when milling the impeller, it is necessary to position and limit the impeller to ensure the stability of the impeller during the machining process and improve the quality of the impeller milling.

[0006] Therefore, we urgently need to provide a rough milling device for impeller production. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] In existing technologies, when milling impellers, it is necessary to position and limit the impeller to ensure stability during the machining process and improve the quality of impeller milling. Please refer to [the relevant documentation / reference]. Figures 1-4The embodiment provides a rough milling device for impeller production, which can effectively position the impeller during the impeller machining process, thereby improving the quality of impeller milling. The rough milling device for impeller production includes a machining table 1, an adjustment and positioning device installed at the top center of the machining table 1, a machining device installed on top of the adjustment and positioning device, and cleaning devices installed at the bottom and left and right sides of the machining table 1.

[0030] The adjustment and positioning device includes an adjustment structure and a positioning structure, with the positioning structure mounted on top of the adjustment structure. The positioning structure includes a fixed plate 105, with a hydraulic cylinder 106 mounted in the center of its top surface. A lifting plate 107 is mounted at the output end of the hydraulic cylinder 106, and a positioning rod 108 is mounted on the center of the bottom surface of the lifting plate 107 near the front end. The adjustment structure includes an asynchronous motor 101, with a transmission component 102 connected to its output end. A rotating shaft 103 is installed inside the transmission component 102, and a turntable 104 is fixedly mounted on the top of the rotating shaft 103.

[0031] The asynchronous motor 101 is detachably installed on the top and bottom surface of the processing table 1. The outer surface of the rotating shaft 103 is installed in the center of the top surface of the processing table 1 through a bearing. The hydraulic cylinder 106 is detachably installed on the center of the top surface of the fixed plate 105.

[0032] By adjusting the settings of the positioning device, the positioning rod 108 is used to position the center of the impeller to be machined, thereby performing center positioning machining on the impeller. At the same time, the machining angle of the impeller is adjusted by the turntable 104, thereby improving the milling effect of the impeller.

[0033] When machining the impeller, the hydraulic cylinder 106 is activated to lift the lifting plate 107, thereby using the lifting plate 107 to drive the positioning rod 108 to abut and position the middle of the impeller. Then, the asynchronous motor 101 is activated to drive the transmission component 102 for transmission. The output end of the asynchronous motor 101 drives the worm to rotate. The outer surface of the worm meshes with the worm wheel, and the worm wheel drives the rotating shaft 103 and the turntable 104 to rotate. Thus, the rotation of the turntable 104 drives the impeller to adjust its angle, thereby effectively improving the milling quality of the impeller.

[0034] Example 2:

[0035] Based on implementation one, the existing technology also has the problem of generating milling debris during the machining process, which can affect subsequent milling of the impeller. Please refer to [reference needed]. Figures 5-6This embodiment provides a rough milling device for impeller production, which can effectively adsorb and collect debris from impeller milling. The device includes a processing frame 201. An electric push rod 202 is mounted on the center of the top surface of the processing frame 201. A sliding block 203 is connected to the output end of the electric push rod 202. An electric push rod 204 is mounted on the bottom of the sliding block 203. A milling assembly 205 is mounted on the output end of the electric push rod 204. The bottom end of the processing frame 201 is fixedly connected to the back of the top of the processing table 1. A rectangular groove is formed in the center of the back of the processing frame 201, and its inner wall is slidably connected to the outer surface of the lifting plate 107. A rectangular hole is formed in the center of the top surface of the processing frame 201, and its inner wall is slidably connected to the outer surface of the sliding block 203.

[0036] The cleaning device includes a collection box 301. An air pump 302 is installed on the right side of the collection box 301 near the bottom. A collection drawer 303 is installed inside the collection box 301. An adsorption tube 304 is installed on the left side of the collection box 301 near the top. An adsorption bucket 305 is installed at the end of the adsorption tube 304 away from the collection box 301. A fan plate 306 is provided on the right side of the adsorption bucket 305. The outer surface of the collection drawer 303 is slidably and sealed to the inner wall of the mounting hole on the front of the collection box 301. The bottom of the adsorption bucket 305 is fixedly connected to the left end of the top surface of the processing table 1. The fan plate 306 is fixedly installed on the right end of the top surface of the processing table 1.

[0037] By using the cleaning device, the cross airflow from the fan plate 306 and the air pump 302 to draw air from the inside of the collection box 301, the milling debris is adsorbed and collected by the adsorption bucket 305.

[0038] During impeller machining, the electric push rod 204 is activated to lower the milling assembly 205, thereby milling the impeller. Then, the electric push rod 202 is activated to move the sliding block 203, which in turn moves the electric push rod 204, allowing for flexible adjustment of the milling position to ensure optimal impeller machining. During machining, the fan plate 306 blows air, creating a horizontal airflow at the top of the machining table 1. Simultaneously, the air pump 302 draws air from the collection box 301, using negative pressure to adsorb debris through the adsorption pipe 304 and adsorption bucket 305. After entering the collection box 301 through the adsorption pipe 304, the debris is filtered and collected by the collection drawer 303, facilitating unified processing of the collected debris and preventing it from affecting subsequent impeller machining.
